Westinghouse AGE

[ibs-jim]

Can anybody tell me how to find out the age of an old westinghouse unit? Model# K180Q31---Style= AP, Serial# MBS12 Thanks in advance for any help you can offer...

Thats probably a Model IK180. 15 ton RTU. Just guessing, its 25-30 years old. If you really need the maufacture date, I should have some old literature at work to decipher the serial number.
